Pattern Division Multiple Access Featuring Amplify-and-Forward Relaying in an Uplink Network
IEEE Access, 2020 NOMA is one of key enabling technologies for prosumer energy management. We studied co-operative techniques useful for establishing pattern division multiple access (PDMA) in an uplink network. In particular, we examined amplify-and-forward (AF) relaying
